You might do some more research yourself. This is an explanation of the name by those who chose to use, not someone like you who put your own meaning on it:
The translation of our name
Many people incorrectly translate our name, “La Raza,” as “the race.” While it is true that one meaning of “raza” in Spanish is indeed “race,” in Spanish, as in English and any other language, words can and do have multiple meanings. As noted in several online dictionaries, “La Raza” means “the people” or “the community.” Translating our name as “the race” is not only inaccurate, it is factually incorrect. “Hispanic” is an ethnicity, not a race. As anyone who has ever met a Dominican American, Mexican American, or Spanish American can attest, Hispanics can be and are members of any and all races.
The term “La Raza” has its origins in early 20th century Latin American literature and translates into English most closely as “the people” or, according to some scholars, as “the Hispanic people of the New World.” The term was coined by Mexican scholar José Vasconcelos to reflect the fact that the people of Latin America are a mixture of many of the world’s races, cultures, and religions. Mistranslating “La Raza” to mean “the race” implies that it is a term meant to exclude others. In fact, the full term coined by Vasconcelos, “La Raza Cósmica,” meaning the “cosmic people,” was developed to reflect not purity but the mixture inherent in the Hispanic people. This is an inclusive concept, meaning that Hispanics share with all other peoples of the world a common heritage and destiny.
And this is not just NCLR’s interpretation. According to the American Heritage Dictionary of the English Language, “La Raza” means:
“…Mexicans or Mexican Americans considered as a group, sometimes extending to all Spanish-speaking people of the Americas.”

Finally, I see you making several references to the KKK in your posting and trying to equate a group know for lynching African-Americans in a dark period of our history.... Bad comparison at best.
That is playbook leftwing spin as to what La Raza is and means. These groups are here in Arizona trying to drive changes in our textbooks and education system that portray this nation as little more than a brutally oppressive negative force in the world. They are behind and involved deeply with the Reconquista and Aztlan movements that believe the Southwestern United States should be returned to Mexican hegemony. The very premise of "The race" is to distinguish Hispanics from all other Americans and to create another branch of identity politics that sets one group of Americans against another. This is not the Italian cultural club cherishing its old world traditions, this is the friendly face of a movement that is literally seditious, deeply anti-American, and openly disdainful of what calls "white culture".
La Raza is left wing in virtually every aspect of its ideology, and I don't mean mainstream left wing, but radical and grotesquely divisive. Its disturbing that you would tout that spin doctor version of the meaning of La Raza as connoting "the people"...if that were the case, the phrase would be La Gente. It quite deliberately is not, and that's because the more genteel term did not convey the kind of divisive and angry ideology that La Raza does...it is not some accident of language, or cultural miscommunication, it is an ideology with deliberate malcontent.
MECHA, an affiliate student group of the La Raza movement, is literally operating within our schools. MECHA, stands for
Movimiento Estudiantil Chicano de Aztlan. Aztlan, being the mythical belief that all of the Southwest belongs...and must be retaken...to the current Mexican nation. Something along the lines of Hitler's call for a return to a "greater Germany". Essentially the return of Texas, New Mexico, Arizona and California to Mexico in a sort of modern day Anschluss.
Its simply incredible that any conservative would be defending these kinds of groups. They are the antithesis of all the conservatism stands for...they seek to elevate qualities of race above those of the intellect and to divide the nation into racial interest groups seeking to rectify the oppressions of American history. Its genuinely racist and genuinely disgusting.
